I agree I have had about 40 cars in my life. As far as factory nothing compares to a bose system. My previous truck was a Lincoln Navigator with that THX Digital Sound or whatever it was. Horrible. I would run your new head unit and then see where you are at. You may want to consider adding a subwoofer with your bose system. I would replace the factory speakers last. Just my opinion.
